Custom opencart slidebanner & banner Module

I want to custome opencart 1.5.6.4 slidebanner and banner module so that it wont use oc_setting table anymore. Instead, it will be using oc_banner table where it will be added with new field like width, height, position and and other and also there will be tools in setting/banner page just like in the slidebanner and banner module. So the controll will be moved to admin banner page.
